Now that Bernie Sanders has entered the contest for the Democratic Party’s presidential nomination, Americans are going to hearing a lot about socialism, because the 73-year old U.S. senator from Vermont describes himself as a “democratic socialist.”

“Ever since I was a kid I never liked to see people without money or connections get put down or pushed around,” Sanders explained in making his announcement. “When I came toCongress I tried to be a voice for people who did not have a voice—the elderly, the children, the sick, and the poor. And that is what I will be doing as a candidate for president."
